Struct Range 

pub struct Range {
    pub start: u32,
    pub len: u32,
}

A block of the value heap. len is zero or a class size.

Fields

start: u32

len: u32

Implementations

impl Range

pub const EMPTY: Range

pub const fn log(self) -> u8

The u8 code stored in object headers: the class’s exponent, with bit 7 set for three times a power of two (len = ((2 | m) << e) / 2); u8::MAX for an empty range.

pub const fn exponent(self) -> u8

Range::log of a power-of-two range.

pub const fn from_exponent(start: u32, log: u8) -> Range

Range::from_log for a code without the mantissa bit (a power-of-two range).

pub const fn from_log(start: u32, log: u8) -> Range
